“I have been advised that there are investigations underway into the capacity of the Dandenong line, however I would not support a cut to V/Line services in order to improve capacity for Metro customers.”

Member for Morwell Russell Northe and Member for Gippsland East Tim Bull also said they do not support the suggestion.

“The Latrobe Valley community’s views are also clear in their objection to such a concept,” Mr Northe said.

PTV is looking for ways to increase and improve services on the Dandenong line, the most congested in the state, through the Dandenong Rail Capacity Program.

The Dandenong line is part of the Pakenham and Gippsland lines.

The program will seek to overhaul train timetabling over the next two years as part of infrastructure changes to combat rising population and demand in the area.
